Hi all,
I have a problem with hierarchy expander column. I have a gridview configured in xaml:

    
                                    <telerikGrid:RadGridView x:Name="rgv01"   
        
                                         telerik:StyleManager.Theme="Office_Blue" 
        
                                         Grid.Row="0"   
        
                                         Grid.RowSpan="2" 
        
                                         MinHeight="400"   
        
                                         RowDetailsVisibilityMode="VisibleWhenSelected" 
        
                                         AutoGenerateColumns="False" 
        
                                         CanUserInsertRows="True" 
        
                                         RowIndicatorVisibility="Collapsed" 
        
                                         CanUserFreezeColumns="False" 
        
                                         ColumnsWidthMode="Auto" 
        
                                         FontSize="9" 
        
                                         IsReadOnly="False"   
        
                                         VerticalGridLinesBrush="#FFFFFFFF" 
        
                                         ShowGroupPanel="False">  
        
                                    </telerikGrid:RadGridView>

I have buttons to select entity type (table) to show that set ItemsSource by code:

    
            // ... Create some data columns on rgv01 here...  
        
            // ...  
        
            rgv01.ItemsSource = dds01.Data;

after a call to a reset code (perhaps to change):

    
                    private void ResetGrid()  
        
                    {  
        
                        rgv01.ItemsSource = null;  
        
                        rgv01.ChildTableDefinitions.Clear();  
        
                        rgv01.GroupDescriptors.Clear();  
        
                        rgv01.SortDescriptors.Clear();  
        
                        rgv01.Columns.Clear();  
        
                    }

All works correctly... on a button (that select a table) I set up a Master/Child relation to show related data (before re-assign ItemsSource property):

    
                        // ...  
        
                        GridViewTableDefinition td = new GridViewTableDefinition();  
        
                        td.Relation = new Telerik.Windows.Data.PropertyRelation("InterviewChoice");  
        
                        rgv01.ChildTableDefinitions.Add(td);  
        
                        // ...

This work correctly too.
Now, if I configure and load a table that hasn't master/detail records to show (plain table) it shows correctly, then if I click button to show (after reset) a table that has master/detail (with a ChildTableDefinition like the code provided) it works fine, shows the expander column, etc... at this point if I click again the button to show a plain table (always after the reset code) the grid still show the expander column (see attached image) that causing a column shift too....! Seems that there are no ways to hide it...I have made a lot of tests...

Perhaps it is a bug or perhaps I missing something in my "reset" code...

Help please!
Many thanks in advance!!
Davide
